Abstract

A number of reactor designs for photocatalytic oxidation in the gas phase are considered: cylindrical reactors with photocatalysts supported by various techniques, a reactor with a vibrationally fluidized bed of a photocatalyst, and a coil reactor with the reactivation of a photocatalyst at regular intervals. It was found that the vibrational fluidization of catalyst grains enhanced catalyst activity because of the effect of periodic illumination of different grain sides. The results of testing of two types of domestic photocatalytic air purifiers commercially manufactured in Russia are reported.
